4440-10-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4440-10-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4440-10:
(6*4)+(5*4)+(4*4)+(3*0)+(2*1)+(1*0)=62
62 % 10 = 2
So 4440-10-2 is a valid CAS Registry Number.
